SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 PM AKDT SUN AUG 5 2012

.ANALYSIS AND UPPER LEVELS...
MAIN FEATURE OF INTEREST IS THE UPPER LOW MOVING INTO THE GULF OF
ALASKA JUST TO THE SOUTH OF KODIAK ISLAND. SHOWERS ARE TAPERING OFF
ACROSS EASTERN PORTIONS OF BRISTOL BAY AS THE LOW CONTINUES TO MOVE
AWAY FROM THE AREA. HIGH PRESSURE IS BUILDING IN ACROSS THE BERING
SEA IN THE WAKE OF THE LOW...BRINGING STRATUS AND FOG TO THE
ALEUTIANS.

.MODEL DISCUSSION...
MODELS ARE IN GOOD AGREEMENT THROUGH THE SHORT TERM REGARDING
POSITION AND EVOLUTION OF MAIN FEATURES. MODELS BEGIN TO DIVERGE
AROUND MID WEEK WITH RESPECT TO POSITION OF THE LOW IN THE
GULF...WITH THE NAM AND ECMWF SOLUTIONS MUCH FURTHER EAST THAN THAT
OF THE GFS.

.SHORT TERM FORECAST...
SOUTHCENTRAL ALASKA...
RAIN WILL PRIMARILY BE CONFINED TO COASTAL AREAS OF SOUTHCENTRAL
ALASKA AS THE LOW MOVES INTO THE CENTRAL GULF. SKIES WILL BEGIN TO
CLEAR THIS AFTERNOON OVER INLAND AREAS AND FAIR CONDITIONS WILL
PERSIST THROUGH MONDAY...WITH ISOLATED SHOWERS POSSIBLE ALONG THE
MOUNTAINS DURING THE AFTERNOON.

SOUTHWEST ALASKA...
SHOWERS WILL CONTINUE TO DIMINISH ACROSS EASTERN PORTIONS OF BRISTOL
BAY AS THE LOW MOVES SOUTHEAST INTO THE GULF OF ALASKA TODAY.
NORTHERLY FLOW ALOFT AND SURFACE RIDGING MOVING IN FROM THE BERING
WILL PROMOTE DRIER CONDITIONS FOR THE SOUTHWEST MAINLAND THROUGH
MONDAY.

BERING SEA/ALEUTIANS...
LOW CLOUDS AND PATCHY FOG WILL PERSIST TODAY AS A RIDGE BUILDS IN
OVER THE BERING. A WEAK LOW PRESSURE SYSTEM MOVING THROUGH THE
WESTERN AND CENTRAL ALEUTIANS WILL BRING A CHANCE OF RAIN ON MONDAY
BEFORE RIDGING MOVES BACK IN.

.LONG TERM FORECAST...
THE CURRENT WEATHER PATTERN LOOKS TO CONTINUE THROUGH MUCH OF THE
WEEK AS THE AREA OF LOW PRESSURE REMAINS OVER THE GULF OF ALASKA.
THIS WILL LEAD TO SHOWERS ALONG COASTAL AREAS AND FAIR WEATHER
CONDITIONS FOR INLAND AREAS OF SOUTHCENTRAL ALASKA. LOW CLOUDS AND
FOG WILL PERSIST ACROSS THE BERING SEA AS HIGH PRESSURE REMAINS IN
CONTROL.

.AER/ALU...WATCH/WARNING SUMMARY
